CORN ER-STAYING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 599,563 dated February 22, 1898.

' Application filed. June 17, 1897. Serial No. 641,121. (No model.)

To all whom, it may concern.-

Be it known that I, HARRY A. INMAN, a citizen of the United States, and a resident of Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Corner-Staying Machines, of which the following is a specification.

My invention relates to improvements in corner-staying machines in making paper boxes, which are applicable to various forms of machines for doing this work, among them to that shown in the Letters Patent granted to Horace Inman and Harry A. Inman March 3, 1896, No. 555,811, to which I refer for a clear understanding of the parts not immediately involved in my present invention, and will confine this specification to a description and illustration of the features constituting it.

The invention relates to improvements in the devices which apply the adhesive mate rial by which the stay strip or piece is attached to the corner of the box. Heretofore it has been customary to apply the adhesive material to the strip itself as it was fed to the corner of the box and immediately prior to its application thereto. In some cases the strip of stay material had been previously treated with adhesive substance and then instead of applying the adhesive material itself to the stay immediately prior to its application to the box water or some other liquid has been applied, which had the effect of softening and rendering sticky the adhesive material with which the stay-strip had been previously treated. By my method I apply the adhesive material not to the stay-strip, but

to the corner of the box, upon which the staystrip, which is fed in a dry non-adhesive condition, is applied. This has several advantages, among them the following: The feeding of a stay-strip which is made limp and sticky by the application of paste thereto, or moisture, if the strip has been. previously pasted, is more difficult than to feed a dry relatively stiff strip; also, when a pasted strip is fed the feeding mechanism is apt to become gummed up or clogged by the paste and has to, be frequently cleaned to keep it in proper working order. I wish it to be understood that I sometimes use a stay-strip which has been treated with adhesive materialsuch, for instance, as starch-for the purpose of stiffening it and making it more easy of application by the machine; but when I do use a stay-strip thus stiffened it is always in a dry condition. No moisture is applied to it until it comes in contact with the adhesive material applied upon'the corner of the box, so that it has all the advantages of --a dry ungummed strip and none of its disadvantages.

By my invention the paste is first applied to the corner of the box, the stay-strip in a dry condition is then applied to the corner, cut 0E, and pressed down upon it, and then the devices which apply the adhesive material to the box on their return movement coat the exterior surface of the stay-piece (which at this time is attached to the corner of the box) with adhesive material, and when it becomesdry it penetrates the fiber of the staystrip and greatly increases its strength and the permanence of its attachment to the corner of the box.

Referring to the drawings hereof, Figure 1 illustrates an endwise view of the parts of a box-staying machine involved in this invention. Fig. 2 illustrates a sidewise view looking from left to right. Fig. 3 illustrates a perspective of the glue-box and rollers. Fig. at illustrates a vertical sectional view of the paste-tank, rollers, and adjacent parts, taken through the center of the roller. Fig. 5 illustrates a side elevation taken from the left, as in Fig. 1, partly broken away to show certain parts in section.

A is the reel for the stay-strip. B is the arm supporting it. C is the box which in my said former patent contains the adhesive material, but in this present instance is merely a support for the feed'rollers D D. E is the delivery-plate and coacting mechanism referred to in that patent. F is the lower blade of the shears. G is the slideway. H is the slide which carries the grooved compressionroller 1. J is the bracket which supports the anvil K, upon which the lower 'die L is supported. These parts are or may be of any preferred construction. That shown in my said patent and illustrated in the drawings thereof is a desirable construction.

Referring now to the parts which constitute the present invention, a is the glue-box. It is open at its upper end, so that glue or other adhesive material may be introduced. It is attached to the forward end of the slide H by a plate D, which is attached to the back of the glue-box, and is rigidly held by a screw 0, which passes through a slot d in the plate I). This slot is provided so that vertical adjustment may be had when required. The box is square excepting at the front side, where there is provided a diagonal extension 6, which is arranged at right-angles to a cutoff eornerfof the box. 011 the inside of the box there is a bracket g, which supports a shaft h, near the forward end of which there is a sleeve or roller 1 held in position by a screw j, which passes through the end of the roller and enters the stud or shaft 7t. Upon the stud hand above the roller or sleeve 2' there is another sleeve is, which serves to locate the roller 1'. This roller, as seen best in Fig. 3, projects beyond the inner surface of the projection 6 through a slot made therein, and its rear or lower side, as seen in Fig. 3, fits closely against, in fact, is practically in contact with, the edge of the slot at that side. At the opposite side, however, on the upper side, as seen in Fig. 3, the periphery of the roller is somewhat removed, say one -sixteenth to one-eighth of an inch from the side of the slot, so that the paste which is within the box would flow therefrom very freely were it not that a scraper or stop device is provided in the following manner:

Zis a piece of spring-brass or equivalent material, at the forward or free end of which a little plate m, made at right angles to the spring part Z, is formed. The spring is attached, as at n, by a screw or soldered to the side of the paste-box, and is provided with an adjusting-screw 0, which passes through a slot 1), made in the spring, and the rectangular or flange-like part at is adapted to press snugly against the side of the projecting part c of the glue-box by means of the slot 1), and the adjustment of the scraper may be made exact by reason of the screw 0. IVhen the screw 0 is run in, the spring is compressed and the flange-like part at is brought into closer contact with the surface of the roller, thus closing more or less of the slit between the roller and the side of the box 6 and limiting the supply of the adhesive material. hen the screw 0 is run back, the reverse action takes place. q is another roller, which is supported upon a bracket 0', which is fastened to the side and lower end of the gluebox a, and is adapted to revolve upon a stud s, set in the end of the bracket and project ing to the interior of the box a. The roller 1 likewise projects through a slot made in the angular end fof the box a, and is provided with a scraper 6, provided with a rectangular part a and set-screw and slot t, the same as before, by which the amount of adhesive material which can be applied to the box by this roller q is adjusted the same as in the other instance.

The operation of the device is as follows: The stay-strip in aperfectlydry condition is fed from the reel A through the feed-rollers D D in the same manner as set forth in my said patent. Upon each forward movement of the slideway and the compression-roller I the glue-rollers carried by the glue box or tank,which is properly adjusted vertically and laterally for the purpose, are brought in contact with the diagonally-presented corner of the box and apply adhesive material thereto. At the proper time the stay-strip is fed forward over the corner. The com pression-roller I then presses the staystrip upon the corner, cutting it off at the same time, and by the return movement of the slideway the compression-roller again presses the stay-strip firmly down upon the corner of the box and the glue-rollers apply a second coating of adhesive material upon the outer surface of the stay-pieces. This concludes the staying of that corner. Another corner of the box is then presented to the machine and the operation is repeated.

It will be obvious to those who are familiar with this art that modifications may be made in the details of construction without departing from the essentials of the invention. I therefore do not limit myself to such details.
